Original strain | UV mutagenesis straina | |
E. coli ATCC 25922 | 5 | 20 |
P. aeruginosa CGMCC1.2620 | 10 | ≥80 |
The method for MIC determination is described in Table 1. Nine P. aeruginosa tachyplesin I-resistant mutants obtained by UV mutagenesis were named the P. aeruginosa UV-1 to -9 resistant strains; one E. coli tachyplesin I-resistant mutant was named the UV-induced E. coli resistant strain.
